Struct ProviderError 

pub struct ProviderError { /* private fields */ }

Lightweight error type for provider implementers.

Implementations

impl ProviderError

pub fn new(kind: ProviderErrorKind, message: impl Into<Option<String>>) -> Self

Create a new error for the given kind with an optional detail message.

pub fn kind(&self) -> ProviderErrorKind

Access the classification of this error.

pub fn message(&self) -> Option<&str>

Optional descriptive message supplied when the error was created.

Trait Implementations

impl Clone for ProviderError

fn clone(&self) -> ProviderError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProviderError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ProviderError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ProviderError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for ProviderError

fn eq(&self, other: &ProviderError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
